Note to self:
If it's a major production, hire a freaking photographer to take some stills.
When I was producing my first ultra-low budget feature, I didn't give a single thought to BTS photos. I was too worried about making a damn movie, BTS stuff doesn't matter!
Except, I learned that those kind of photos actually are useful in promotion, and more importantly (in my opinion), this is a time that you'll want to remember. So, if you can't afford a pro, just tell a friend to show up, stay out of the way, and take as many pics as possible.
Thanks for sharing the pics, everybody.
